You were saying that the routes were appearing only in the route cache. if the
route cache is gone can you summarize what the problem is now?

If kernel is trying to resolv the IP X localy and it appears in arp cache then
I don't see what is it doing wrong.

Also what are the contents of the routing tables and whether there is any
difference between the state when running bird and when bird is shutdown?
